FAN0 not turning on #11

Closed phongshader closed 4 years ago

phongshader commented 4 years ago

If I run a m106 command FAN0 does not turn on however FAN0 led does light up. The voltage at the fan terminal after a m106 s255 is 1.39 and s128 is .93, s0 is .10. I have a 12v power supply and the power select is jumped to vin-vout. I tried vout-12v with the same result.
